Specification of Letters Patent.

Patented May 18; 1909.

Application filed April 2'7, 1908. Serial No. 429,417.

To all whom it may concern:

Be it known that. we, Hanna A. SCHNEL- nAon, a resident of Grafton, in the county of 1 Allegheny and ,State of Pennsylvaniafand I and eflicient means blow pipe so as to prevent the twistin or distorting of the glass in the mold; whic sometimes occurs where theb'low'pipe is-rota'te'd continuously in one direction.

0 these ends our invention comprises the novel features hereinafter set forth. and claimed.

In the aocompanyin drawings Figure '1 is a side elevation of ag lass blowing machine.

embodying our invention; Fig; 2 is a cross" section on the hue 2-2 Fig. 1 Fig. 3 is an enlarged detail.

'VVe have shown our invention as applied to an ordinary form of glass blowing machine, and as the construction of the machine in itself forms no. part of our invention wewi only refer to the same generally.

The numeral 2 designates the port of'the machine which may be mounted naled in suitable bearings on wheels 3 for transporting the machine from one point'in the factory to another;

Supported on "the base 2 is the pillar 2 to frame 4 is secured, said frame be which the ing vertically adjustable in suitable guides 5 on the pillar 2. On the frame 4 is-t'he shelf 6 which forms the support for a suitable elec tric motor 7. A belt 8 connects the motor shaft with the pulley 9 onithe shaft 10. jour- 11 on the frame 4. Shaft 10 is connected by belt'to a counter shaft 10*. Secured to the counter shaft 10 is the worm 12 which engages the worm wheel 13 on the vertical shaft 14. This shaft 14 is stepped at itslowcr end in the base'2. and said shaft at its upper end passes through the sleeve 15 on the frame -4.

and useful Improve:

base or sup The tablef16 is secured to the shaft 14, said table carrying the molds 17 which are arranged atproper intervals around the outer edge ofsaid table 16.

Keyed to the shaft 14 is the ring '18 strengthened bythe radialarms 19. 'At suit-.

. able intervals 1n the ring 18 are the sleeves 20 which are provided witlrthe rotary bushings 20*, said bushings being provided at their upper ends with the friction beveled-collars 21 which may be formed of some fibrous material to provide the necessary friction. These collars 21 are held in place by means of the bindingnuts 22 .which engage the threaded necks 23' on. the bushings 20. Extending down through the bushings 20 are the pipes 24 which convey the air to the blow pipes, said pipes 24 being connected by flexible connections 25 to the air chambers 26 to which air is supplied in proper quantity. The

- sockets 27 on the lower ends of the (pipes 24 are adap blow pipes 28.. The pipe ted to engage the'upper en set the 24 is vertically movable in the bushing 20; and to provide for hthis vertical movement .of the pipe 24 in bringing "the sockets 27 into, engagement with the blow pipes and releasing them therefrom, the levers29 The outer-ends of the levers 29 are pivoted-to the up or ends" of the pipes 24. The outer ends 0 the levers 29 have the friction wheels 11 32 thereon which are adapted to travel along the-cam 33. v

A fixed ring 34 is provided with the sleeve 35 which passes up within-and is connected to the sleeve 15011 the frame 4. The eriphery of this the recesses 36 beveled-faces 37.

Arc-shaped arms 38 are secured by bolts 39 to the frame 4, said arc-shaped arms having the frictional contact beveled faces 40, said faces being arranged opposite the recessed portions 36 of the ring 34.

Carried by the shaft 14 are which are supported by the collars 42 on said shalt, said racks at their outer ends being ada )ted to receive the blowpipes 28.

hen our improved machine is in use the blow pipes with the molten glass on the end thereof are inserted in the racks in such position as to bring the lower ends of said which form the prO ecting- OF PITTSBURG, PENNSYI,

fixed ring 34 is provided with the racks 41 blow pipes into proper position with reference to the open mold, whereupon the mold is closed and the socket 27 is lowered auto- 5 in connection with the cam 33. The blow pipes are arranged to be inserted at the front of the machine. and while the machine is in operation and the table carrying the molds as well-as the ring 18 main course of rotation. The mold after being closed moves around until the blow pipe comes into the space between .the ring 34:. and the arcshaped arms 38, and the frictional faces/i0 and 37 will alternately engage the friction 1-5 collar 21 of the bushing 20 and so impart an oscillatory movement to said bushing which in turn communicates a like oscillatory movement to the blow pipe 28-.- By having these frictional faces arranged inthe man- 20 ner shown it is apparent that while one of the frictional faces 40 is in engagement with the friction collar 21 the blow pipe will be rotated in one direction and when said friction collar comes in contact with one of the frictional 25 faces 37 the blow pipe will be rotated in an opposite direction. the blow pipe in one direction may be readily regulated by the length of the frictional faces andin this way the oscillatory move ment may be increased or diminished. This oscillatory movement will be imparted to the blow pipes as long as they move within the space between the ring 345 and the arcshaped arms 38 and when'they pass therefrom the mold will be opened and the blow pipe removed and another inserted to take its place. These operations ofthe machine,

however, are well known to those skilled in "the art and it is not deemed necessary to re- 40 fer to the samein further detail.
